This invention relates to locking means for easement windows and it isanobject of the invention to'- provide a device of thiskind which can beemployed withequal facility at the rightor left side of the window.

It is also an obj ect of the invention to :pro-

locking member carried Vby the Casement frame orother stationarypartifo-r engagement with` the window .when inr closed posiment. i y ,Yt c The invention consists in the details of construction and inthecombination and arrangement of thel several partsV of my improvedlocking means 'for easement windows whereby Certain important advantagesare attained andthe device rendered simpler,lessexpen sive and otherwisemore convenient. and advantageous forfuse, as will beihereinafter morefully set forth. Y n The novel features of my invention will hereinafterbe definitely claimed.

`Inorder that my Vinvention may be the better understood, rvI will nowproceed to describe the same with reference to the accompanyingdrawings, wherein 4 y Figure l isa fragmentary elevational viewillustrating a locking meansV constructed in accordance with anembodiment of the invention;

.Figure .11` is anV elevational i view 4,of the -mounting washerremoved; tion tohold the same lagainst openingmove- Wl is in closedposition. rEhe outer portion Vofthe plate?) is formed toprovide'aninwardvl-y `facing cylindrical housing 4A overlapping the closing faceofthe swinging sash ormember 'WJ :The housing 4 is provided at the aXialYcenter of its outerwall with a relatively large `opening 15V. Arrangedwithin the 'housing 4 is a cylindrical head one end portion of whichextends through the opening 5 Vwhile the opposite or inner vend of thehead 6 has disposed radially thereacross and intedrally formed therewitha locking bar 7 the i ends 8 of which are inwardly beveled.

A'portion of the head 6 within the housing 4 is Vprovided Vwith anoutstanding circular flange 9` with which engagesa cup member` l0 snuglyreceived within the housing 4*through y 'the inneropentface thereoflThis -cupmem-vj ber 10 serves to maintainV the head 6 in ap-V pliedvposition with respect tothe housing 4, yet permits the same-to'haverequisite rotation. Theiouterface of the member 10 is provided with the`radial slot '11. having its injtermedi ate4 portion transverselyenlarged beyond opposite sides thereof as at 12 to facilitatethe desiredassemblyfof the member 10 andy the head 6 with vrespect to the housing4.` Interposed between the Hange 9and the Vadjacent outer wall14 of thehousing 4is an 9is a sectionalview taken substani l tially on the line 99 of Figure 8; d' Y vide a device of this kind comprising a rotary ingmember lf2 of the sash W when the sash f undulated spring washer whichserves to provide effective means to retain the head 6 in its differentpositions.

The outer end of the head 6 is continued by an ear or lug 16 to which isadapted t0 be operatively engaged a desired operating memberdiagrannnatically indicated at 17 in Figure 4. Y

Secured to the member 1a of the sash W b y the'screws 13er the like isan engdportionv of a plate 19 also disposed inwardly of the sash l andwhich, when the sash "W is in closed position is in overlying relationwith' respect to the plate 3 and more particularly the housing 4. Theinner or free end portion of the plate 19 is provided with an ovalshaped opening` 2O through which the bar 7 is adapted torbe disposedwhen said bar 7 has its longitudinal axis disposed in the same generaldirection as the major anis of the opening 20.

Upon turning movement of the bar 7 and preferably a quarter turn it willbe readily noted that the window W7 will be effectively locked in fullydisposed position. firs illustrated in Figure 4, it is to be notedthatthe marginal edgeV defining the opening 2O is closed on a bevelcomplimentary to a bevel on the edge of the bar to facilitate vtherequisite locking coaction between the bar 7 and plate Y lt is to benoted that a locking means as herein disclosed is of a character topermit the same to be used either right h and or left aand and which isof material advantage both -with viewpoints of production andapplication.

In the embodiment of my invention asillustrated in Figures 8 to 12inclusive l employ a housing 4 comprising a pair of spaced plates 21 and22 having their outer margins connected by an interposed plate 23 andthe -opposite ends thereof closed by the interposed plates 24. rlheouter corner portions of the housing 4 are preferably cut away,

as at 25, so that the interior of said 'housing may be maintained freeof such dirt or the like which may have a tendeney to interfere hoilined by the outstanding flanges 26 which arep aligning openings 27 withthe eil'ective operation of the locking plate 7 ln other words, the cutout portions provide convenient cleanoutopenings.

The inner face of the housing 4 is open'and the side plates 24 arecontinued by the eXtended portions 24 which are disposed a desireddistance beyond the open inner face of the 4 and the flanges 24 and 24are deinwardly disposed boss 28 carried by the'central portion of asupporting Washer 29. rlhis boss 28 and washer 29 have disposedtherethrough an opening 3() angular in cross section and through whichis snugly directed a shank 31. This shank 31 is also snugly directedthrough an opening 32 formed in an end portion of the locking plate 7with the head 33 of the shank 31 having Contact with lthe inner or rearface ofthe locking plate 7.

ing 27 in the inner or rear plate 2-1 after the plate 7. has beenproperly inserted within the housing` 4 through the inner open facethereofand the mounting Washer 29 has also been applied. After the nut34 has been properly engaged upon the shank 31 the locking plate 7 willbe eectively supported within the housing 4 for rotation with the shank31.

The shank 31 is of a length when applied to extend a material distancebeyond the outer face of the housing 4 and the free end portion of theshank 31 is cylindrical in' form, as at 37, with'` its peripherypreferably smooth and unobstructed. VThis portion 37 of the shank 31` issnugly engaged within a socket or recess 33 provided inl the inner faceof a head 39 and keyed thereto by apin 40 orV the like. The head 39 hasthe marginal portion of its inner face deiined by a skirt 41 dis posedEin adirection toward the washer 29 and which serves to substantiallyhouse or enclose the applied nut 34.

Pivotally connected, as at 42, with the `outer portion of the head 39 isan operating handle 43 which provides convenient means to impart therequisite rocking movement to the shank 31 and the locking plate 7.

The frame F has associated therewith an out-swinging. sash S and theout-swinging vertical member 1b thereof at a desired point thereon hasbolted as at 44, or otherwise securely attached thereto 'an outstandingkeeper 45 which, .when the sash S is in applied positionwith respect tothe frame F, proand facility with whichit may be assembled and operated,and it will also be obvious that my invention is susceptible of somechange and modication without departing from the principles and spiritthereof and for this. reason I do not wish to be understood as limitingmyself to the precise arrangement and formation of the several partsherein shown in carrying out my invention in practice except ashereinafter claimed.
